Safety device for revolvers

ABSTRACT

A SAFETY DEVICE FOR REVOLVERS FOR THE PREVENTION OF ACCIDENTAL DISCHARGE. THE DEVICE IS MOUNTED DIRECTLY ON THE HAMMER AND CONTROLLED BY THE TRIGGER. IT CONSISTS OF: A BALANCE LEVER PIVOTABLY CONNECTED TO THE YOKE AND HAVING A LOWER FINGER AND AN UPPER APPENDIX AND ANGULARLY MOVABLE IN A PLANE PARALLEL TO THE BACK FACE OF THE YOKE, A PUSHER AXIALLY MOVABLE AND COOPERATING WITH THE TRIGGER&#39;&#39;S BLOCKING TOOTH, AND AN INCLINED UPPER SURFACE NEAR THE UPPER EXTREMITY OF THE PUSHER FOR POSITIONING   THE BALANCE LEVER BETWEEN THE HAMMER AND THE BACK FACE OF THE YOKE.

89/ Int. Cl. F41c 17/00, 17/08 US. Cl. 4266 3 Claims ABSTRACT OF THEDISCLOSURE The present invention relates to safety devices for firearmsand, more particularly, to safety devices for revolvers.

In the field of revolvers, safety devices are Well known for the purposeof preventing accidental discharges due to the dropping of the firearmor due to the carelessness of the operator while handling the revolveror the hammer thereof. However, the known safety devices are oftenunsatisfactory and not at all fool proof and do not comply with thestringent safety regulations of many states.

It is therefore the main object of the present invention to provide fora revolver on the hammer of which there is mounted a pushing elementcontrolled by the trigger. The arresting tooth of the trigger is causedto engage a notch suitably provided in the body of the hammer, so as toobtain the safety position of the firearm. This engagement in the notchin the body of the hammer serves to determine the angular displacementof a balance lever pivotable in the back face of the yoke of therevolver, so as to interpose itself between the yoke and the hammer andto limit the degree of displacement which will then result in theprevention of the operation of the firing pin upon the projectile.

Briefly stated, the present invention, therefore, provides in a revolvera safety device which comprises means to control and limit thedisplacement of the hammer, so as to preclude fully the even inadvertentfiring of a projectile, said safety device consisting essentially of alever element which is interposable between the hammer and the yoke ofthe revolver.

Another object of the present invention is to provide for a revolverwherein the disengagement of the safety device requires a willful anddetermined action upon the hammer to bring the latter in the cocked orarmed position or in an intermediate neutral position between the fullysafe position and the firing position.

These and other advantages of the invention will be apparent from thefollowing detailed description thereof and from the accompanyingdrawings, in which:

FIG. 1 is a perspective view of the revolver of the invention;

FIG. 2 is a sectional view of the safety device in the operationalposition;

FIG. 3 is a sectional view taken along the lines A-A of FIG. 2;

FIG. 4 is a sectional view taken along the lines B-B of FIG. 3;

nited States Patent FIG. 5 shows the detailed sectional view of FIG.-3,but in the safety position; and

FIG. 6 is a sectional view taken along the lines CC of FIG. 5.

Referring now to the drawings, hammer 1 is actuated by spring 2 andcooperates mechanically with trigger 3, the arresting tooth 4 of whichacts upon upper notch 5, intermediate notch 6 and lower finger 7,elements 5, 6 and 7 being provided in the hammer and constituting thesafety position, the neutral position and, respectively, the armedposition of the hammer.

The present invention provides for a longitudinal seat 9 in the body ofthe hammer, within which seat is positioned a piston-pushing element 10which is free to effect axial displacements when actuated by head spring22. These displacements are defined by a transverse pin 11 acting incorrespondence with an indentation .12. The pushing element 10 protrudesin its lower part in juxtaposition with the upper notch 5 of the hammerand, in the vicinity of its upper part is provided with an inclinedplanar surface 20 in juxtaposition with the laterally carved indentation21 of the hammer. The inclined surface 20 serves the purpose of actingupon the lower finger 14 of the balance lever 13. Lever 13 is pi-votablein turn on 15 within a seat or notch 16 suitably provided on the backface of the yoke 17 of the revolver. The balance lever 13 is actuated,underneath, by a spring 18 positioned within the body of the yoke, so asto counteract the action of the inclined surface 20 of the pushingelement 10 and to act, therefore, on the finger 14 of the lever itself.This lever terminates, upperly, in an appendix 19 which is preshaped andis capable of interposing, as a finger, between the hammer and the yoke,due to the angular displacements of the lever 13, which displacementsare in a plane substantially parallel and adjacent to the back face ofthe yoke, against which the hammer acts.

To set the revolver in the safety position, it is suflicient to effectan angular displacement of the hammer 1 sufiicient to seat the blockingtooth 4 of the trigger 3 within the upper notch 5 of the hammer. Due tothe reaction of spring 2 of the trigger, this will cause an axialdisplacement upwardly of the pushing element 10 provided in the hammer.To this displacement of element .10 corresponds the action of theinclined surface 20 thereof upon the finger 14 of the balance lever 13,see FIG. 3, with the resultant angular displacement of the lever 13 soas to bring the upper appendix 19 between the front surface of thehammer 1 and the back surface of the yoke 17, see FIG. 4.

Because of the above, the hammer is prevented from moving fully towardthe yoke, so that the projectile cannot be acted upon as a result of theincomplete movement of the hammer and the revolver cannot be discharged.

The disengagement of the safety means, conversely, requires the willfuland determined intervention of the operator, so as to move the hammerinto the proper armed or cocked position. This will occur when thepushing element 10, freed from the action of tooth 4 of the trigger andactuated by the head spring 22 returns downwardly and allows balancelever 13 (see FIG. 5), actuated by back spring 18, to be in the positionwhere the upper appendix 19 is blocked in the notch 16 of the lever (seefigure 6), so as not to interfere with the movement of the hammer.
